The third is probability 0. This is a continuous function and the probability of any single exact point is 0.
\n" ); document.write( "z=(x-mean)/sd
\n" ); document.write( "z > (70.7-63.5)/7.2=1
\n" ); document.write( "probability z > 1 is 0.1587
\n" ); document.write( "-
\n" ); document.write( "z < (50.54-63.5)/7.2
\n" ); document.write( "=-12.96/7.2
\n" ); document.write( "=-1.8
\n" ); document.write( "probability z < -1.8 is 0.0359
\n" ); document.write( " \n" ); document.write( "
